Howdy, I bought a new Nokia 6225 CDMA phone with a genuine Nokia car kit (only $49 extra from Telstra at the moment) and I'm a bit bewildered at the options available for external CDMA antenna's. I've had a good poke around the archives and saw a lot of RFI 1795 fans, but not much mentioned about the big ones.
A 2.1m one was recommended as the best by a reputable company, but will set me back about $220 with base. This may be just too high for practical application so does extra height and price really make a significant difference?
Can anyone recommend a particular model? Any good people to see in
Perth for price/advice on said item?
Cheers

Hi V8Diesel,
I too have the Nokia 6225 with full car kit and RFI 1795 antenae (approx 800mm long). On my UHF, I run a 2.1m aerial when out of town and have noticed a significant improvement in range. My UHF experience has shown the taller the antenae, the better the range (and noticeably better, not just a minor improvement).
But to translate that to CDMA experience is not straightforward. Due to their nature, CDMA has a finite distance (approx 100kms from a base station), unlike UHF. So while the bigger CDMA antenae cannot extend the range greater than 100kms, within the 100 km boundary it will give better chance of reception depending on terrain. This is purely due to the extra height to get your signal higher up. You would be just as
well off putting a standard CDMA antenae on an extension pole!!!
Personally, I would stick with the RFI 1795 for the CDMA, but I do like my 2.1m UHF when out of town (gotta watch those tree covered tracks though!).
Cheers

PS. Currently in London at the moment, haven't seen a single car phone antenae here at all, range does not seem to be a problem! Everyone seems to run bluetooth ear pieces here.
